Chat and background model roles effectively swapped during the conversation+curator pivot, but call sites still used OLD routing. This commit re-routes each call to the model whose new role fits. Moved to background_model (worker — heavy, deliberate): - services/journal_prep.py: daily prep generation. - services/user_profile.py: observation consolidation. Moved to default_model (chat — small, fast): - services/chat.py save_response_as_note: note title generation. - services/tag_suggestions.py: tag suggestions. Already routed correctly (unchanged): curator, closeout, consolidation, project summaries, history summarization. SettingsView.vue: help text rewritten for both model fields to describe new roles. Background Model UI label renamed to Worker Model so the heavier role is visible from the picker. Warning copy updated to recommend OLLAMA_MAX_LOADED_MODELS=2+ so chat and worker can stay loaded simultaneously. Schema names default_model and background_model unchanged on purpose (renaming requires migration + touches ~50 call sites for UX-only gain).
